Analysis of MgO Nano Particles and Its Deposition on Steel by Cold Spray Process

In the present scenario, steel has become an important part of industry due to its extensive applications in automotive, household appliances, business machine and heavy construction such as marine and chemical industries. Magnesium oxide nano particles are odourless and nontoxic. They possess high hardness, high purity and a high melting point. It is the popular material used in the applications automotive, aerospace, sports equipment, and electronics industries. Heat treated mild steel at 800 degrees C shows rough surface roughness and shows fine surface when compared with 600 degrees C. Surface roughness is higher after deposition of MgO nano particles on mild steel at 800 degrees C when compared with 600 degrees C. Surface roughness is low after deposition of MgO nano particles on mild steel at 600 degrees C when compared with base metal. The hardness of the base metal is low when compared with heat treated mild steel at 600 degrees C. Heat treated mild steel at 800 degrees C shows high hardness when compared with base metal. The hardness of the coated sample at 600 degrees C is moderate when compared with base metal due to deposition of MgO nano particles on mild steel. When compared with base metal the coated sample at 800 degrees C shows high hardness because of maximum deposition of MgO nano particles on mild steel. The hardness is high after coating nano particles on mild steel at 800 degrees C. (C) 2018 Elsevier Ltd. All rights reserved.
